N ITED SPINDLE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent 110,613,112, dated October 25, 1898.

Application filed January 7, 1897. Seri l N0- 618,297. (No model.)

To all whom it may concern:

Be it known that I, THOMAS ALEXANDER BOYD, a subject of the Queen of Great Britain and Ireland, and a resident of Glasgow, county of Lanark, Scotland, have invented Improvements Relating to Spindles for Spinning-Machines, of which the following is a specification.

My invention relates to improvements in what are generally known as self-contained ring-spindles (most of which are made on the self-balancing principle) of that kind in which each spindle is carried by two sockets 'i. 6., an internal step-tube socket-piece and an external oil-cup pedestal socket-piecein which when the spindle is running the oil circulates through openings in the internal socket, so as freely to lubricate its spindlebearings. The external pedestal-socket is formed with a collar to rest upon the spindlerail and is secured to the latterby a nut screwed upon a part of the socket projecting downward through a hole in the rail, by which it can be adjusted, so that the perpendicular axis of the spindle may be set as nearly as possible in the exact centerof its ring during the whole traverse of the ring, which is very important. The hole in the rail is made for this purpose a little larger than the part of the external pedestal socket which passes through it, so as to have the required amount of adjustment.

When spindles of the kind above described require cleaning, the usual custom is to remove the spindle and theloose internal socket and pump the dirty oil out of the external pedestalsocket. This, however, is not satisfactory, as it occupies too much time, and it does not always thoroughly remove the dirty oil. oughly to cleanse the external pedestal-socket it is unscrewed and removed from the rail and emptied and washed out; but this also is obviously objectionable, as it necessitates its being carefully readjusted and tightened up in the center of its ring.

The chief object of my invention is to overcome the above objections, so as to make the oiling and cleansing of the external oil-cup socket more convenient and more satisfactory.

My present improvements are shown in an accompanying sheet of drawings and are here So in many cases in order thorinafter described with reference to said drawlugs.

Figure 1 is a side elevation of the improved spindle, showing in section the part of a spindle-rail in which the spindle is adjustably fixed. Fig. 2 is a sectional viewof same. Fig. 3 is a plan view of the spindle-pedestal. Figs. at, 5, and 6 are a frontview, side view, and plan. Figs. 7, S, and 9 are front, side, and plan views of other applications of my 131'6S611hl'l11- provements referred to.

Similar numbers of reference designate corresponding parts throughout.

In carrying out my invention the internal step-tube socket-piece 11, Figs. 1 and 2, is combined with its external oil-cup 12 in the ordinary way and for the purpose above described, and I make the pedestal part of the socket-piece 13 also as described with this exception, that instead of making the oil-cup and pedestal all in one piece, as usual, I make them in two separate parts-2'-. 6., a pedestalsocket part 13, which can be adj ustably fixed in the usual manner to the spindle-rail 14: by a nut 15, and a separate external oil-cup socketpiece part 12, which is put in from above and passes through the pedestal part, and by means of a shoulder or collar 16, on which it rests, is carried by the pedestal part 13, or the two parts may be tapered to fit one another, so that the oil-cup socket part can be easily removed therefrom for oiling. The external cup-socket 12 when made in this improved manner besides being more satisfactory and convenient requires no readjustment when for the purpose of cleansing or any other purpose it is taken out and put back in its place, as it fills nicely the hole formed to receive it in the center of the pedestal 13, and owing to the length of its bearing in the latter the spindle 17 is held correctly in its working position without the aid or necessity of nuts or screws of any kind. A leather washer or a pin may be used to prevent the external cup-socket 12 turning in its pedestal-socket 13by the action of the revolving spindle 17 should it be found necessary; and for this purpose a pin 18, which may be put in the collar 16 of the external cup-socket 12, is let into one of the slots 19 or 20, Fig. 3, on the top face of the pedestalsocket 13, and by putting the pin sometimes into one slot and sometimes into the other the external cup-socket is partly turned around, so that a more uniform wear and longer duration of its internal step-tube socket 11 is obtained when the latter is so made that it always occupies the same position in relation to its external cup-socket 12.

My improved pedestal socket combined with its external and internal socket, though specially designed to be used for ring spinning and twisting, can also be used to advancage in some cases for flier spinning and twisting machines.

In the case of flier-spindles and other spindles which for various reasons may not require any careful central adjustment when being fixed in their working position on their spindle-rails it is not necessary to have the holes in the spindle-rails any larger than the part of the pedestal which passes through it, and in cases of this kind if the spindle-rails 21, Figs. 4, 5, and 6, be made with holes deep enough, or in the case of box-rails 22, Figs. 7, 8, and 9, if the top and under holes be made far enough apart, and if these be carefully spaced to the pitch of machine and correctly bored to fit the diameter of my improved eX- ternal oil-cup socket, the latter may be used to advantage alone in combination with its internal step-tube socket 11, as described, without the pedestal-socket 13-that is, the rails will form the direct supports for the combined oil-cup socket and step-tube socket, which are inserted from above. The external and internal sockets 11 and 12 in combination may also be used with many other forms of rail-brackets. Myimproved pedestal-socket may also be made inone piece with bracket-like castings, required for stopping spindles with or without automatic motion, similar to what is shown and described in the specification of British Letters Patent No. 19,036 of 1889.

Another part of my present invention relates to an improved self-acting spindle-catch 23 of the kind described in the specification of British Letters Patent No. 18,920 of 1888, the object of which is to prevent the spindle 17 being lifted out of its place when doffing. My improved catch is by preference loosely jointed behind the spindle to an upwardlyprojecting part 24 of the pedestal-socket 13; and myimprovement consists in making and arranging the catch 23 and its details so that the operator instead of, as formerly, requiring to use both hands, one to release the catch and the other to lift the spindle, can with the thumb and the finger of one hand simultaneously and conveniently release the catch 23 and lift the spindle 17 out of its socket. For this purpose and also for the purpose of giving more room to the building-rail when down at its lowest point my improved spindle-catch 23 is centered lower down than formerly, but, as in the former case, it is made with a bevel 25, by acting on which the spindle 17 pushes it aside when being put into its socket 11, while atail 26, formed at the back of the catch, acts as a weight to return it into its catching position, as shown in the drawings, as soon as the spindle is down far enough, so as to prevent the spindle'from being lifted out of its socket till the catch is released by the hand of the operator. Instead, however, of engaging with the upper surface of the top flange 27 of the spindle-pulley for this purpose my improved catch engages with part of the top surface 28 of the under flange of the pulley of the spindle.

The otherobject of my present invention referred tois verysimplyobtained by making the spindle-catch 23, with the part 29, projecting a short distance above the horn or upwardlyprojecting part 24, on which it is pivoted. On this projecting part 29 of the catch the thumb and forefinger of the operator can act, so as simultaneously and conveniently to release the catch 23 and lift the spindle 17.

I claim as my invention 1. The combination of an internal steptube socket-piece with an external oil-cup socket-piece and a support into which the oilcup socket-piece is removably inserted from above and a shoulder on the said socket-piece to sustain it in the support, substantially as described.

2. A spindle provided with a pivoted catch having a beveled part 25 to be acted on by the whirl, a tail 26 to tend to maintain it in position to retain the spindle and an up; wardly-projecting portion 29 so located that it may be acted on by the thumb or finger of the same hand of the operator which grasps the spindle, whereby the catch may be re leased by the same thumb or finger which is used in grasping the spindle, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOMAS ALEXANDER BOYD.
